Granted, I am not a pet owner (or, as they call them here in San Francisco, "pet guardian") and I don't have kids, but I really have a mistrust of people who adopt exotic animals because they want them as pets, not because they are caretakers or animal rescuers. These people are totally indulgent and also totally irresponsible. That lady who removed the teeth out of that monkey deserves serious jail time.
On another note: Didn't the movie "Outbreak" begin with somebody illegally importing a pet monkey to the U.S. and it starts spreading this horrific airborne disease? Sure, it was an over-the-top plot device, but it makes you think twice about smuggling strange creatures onto our shores. Why aren't these people remotely scared about that kind of thing?
